What is Ethereum 2.0

Ethereum, which is touted as the second most popular blockchain platform globally, seeks to differentiate itself from Bitcoin by overcoming some of Bitcoin's inherent limitations. Bitcoin's reliance on the proof-of-work ( PoW ) consensus algorithm and its scalability challenges hampered Ethereum's progress.

To overcome these hurdles, Ethereum is undergoing gradual improvements, including the implementation of Beacon Chain, Merge, and Shard Chains. The upgrade aims to improve the scalability and security of the Ethereum network through various infrastructure modifications, most notably the transition from PoW to a more efficient proof-of-stake ( PoS ) model.

Created by Ethereum creator Vitalik Buterin in 2013, Ethereum was envisioned as a blockchain platform capable of supporting a wide range of applications beyond finance. Buterin envisions a world where decentralization can empower developers to create governance systems, lending platforms, databases, and digital representations of physical assets.

However, Ethereum currently faces scalability challenges, resulting in delays and high transaction fees, hampering its potential to revolutionize the global network.

Recognizing this challenge, Buterin, along with Ethereum developers and the Ethereum Foundation, is leading the initiative for Ethereum 2.0, or Eth2. This upgrade aims to address Ethereum's scalability issues and improve its speed, security, and accessibility. Since 2020, Ethereum developers have been working hard to implement these improvements, which aim to make Ethereum faster, safer, and more accessible than ever before.

What is Ethereum 2.0?

Ethereum 2.0 represents a significant change in the network's consensus algorithm, a transition from PoW to PoS. This transition offers many benefits, including improved scalability, security, and accessibility.

Proof-of-stake vs proof-of-work

In the context of blockchain consensus, PoW is the original method implemented by Bitcoin. In PoW, miners solve complex algorithms to validate blocks, consuming large amounts of computing power and electricity. This process is not environmentally friendly and expensive.

In contrast, PoS relies on validators staking cryptocurrency to validate transactions, offering a more energy efficient and accessible approach. Validators earn rewards based on their participation, which contributes to the security and scalability of the network.

Once the upgrade is complete, Ethereum will benefit from PoS, improving its scalability, accessibility, and security while reducing its environmental impact. However, the transition to Ethereum 2.0 is a complex effort that requires extensive user involvement and time for changes to take effect.

Ethereum vs. Ethereum 2.0

The main difference between Ethereum PoW and Ethereum PoS is that PoS is much more energy efficient, requiring less CPU power to secure the blockchain.

What's more, Ethereum 2.0 is much more efficient than the original Ethereum, able to handle up to 100,000 transactions per second compared to its predecessor's 15 transactions per second. It is worth noting that a proof-of-work version of Ethereum called ETHPoW was also launched after the Merge, still using the PoW consensus mechanism to validate blocks.
